Ultraman: I Exploit a System Bug and Become Invincible

It's written quite well, but the attribute data is prone to errors, and from what I've seen so far, it does seem to be starting to go wrong. However, the book is still readable.

The data is poorly written, with no clear level boundaries; it's just endless scrolling.

Writing this kind of thing is easy to mess up.

Why are the side effects gone?

Good

It's utterly worthless. Aside from a bunch of unfunny, nonsensical, and vulgar jokes, there's not a single substantial plot point. Aside from the system manipulating data, the protagonist shows no growth whatsoever. After skipping the cheesy plot, you finally get to the main storyline and discover that there isn't a single normal person. Everyone's character is completely distorted.
